Hey guys.
For a few years now that I've used a a set of 2x4GB G.Skill RipjawsX DDR3 (F3-12800CL9D-8GBXL) with no issues at its tested speeds, timings and voltage (http://www.gskill.com/en/product/f3-12800cl9d-8gbxl).
Last week I dediced to buy another identical set of 2x4GB, also F3-12800CL9D-8GBXL, and added it to the remaining slots on the motherboard, making it a 4x4GB.
The problem is that if the RAM is running at 1600MHz (the speed they should run at) it is completely unstable with several BSODs and Prime95 giving a fatal error on all workers just after 5 seconds of running the Blend test.
Settings I tried but still not stable:
- Running at higher RAM voltage: instead of 1.5v - 1.51v, 1.52v, 1.53v etc (1.58v+ makes windows restart at logon).
- Running with everything on Auto in Bios, it sets timings to 11-11-11-28-2T-1600Mhz. On Prime95 it takes longer to crash the test, but still not stable.
Settings I tried with stable RAM:
- Running with 9-9-9-24-2T at 1333MHz or 1400MHz.
Can I do something to be able to run the RAM at the specified timings and frequency (9-9-9-24-2T 1600MHz) ?
Thank you.
Motherboard: Asus Z87-PRO
CPU: Intel i5 4670k
RAM: 2 sets of 2x4GB G.Skill RipjawsX 1600MHz (4x4GB)
EDIT: Looking at CPU-Z there is only one difference from the new set to the old set. On the timings table, the value for the tRC on the XMP-1600 column is 33 for the new set and 40 for the old.
